Fullmetal Alchemist

are two alchemist brothers who search for the legendary Philosopher’s Stone, a powerful object which would allow them to recover their bodies (which were lost in an attempt to bring their mother back to life through alchemy). Born in the village of Resembool from the country of Amestris , the two brothers lived there with their parents. Their father, Hohenheim, left home for unknown reasons and years later, their mother, Trisha Elric, died of a terminal illness leaving the Elric brothers alone. After their mother’s death, Edward becomes determined to bring her back through the use of alchemy, an advanced science in which objects can be created from raw materials. They researched Human Transmutation, a forbidden art in which one attempts to create or modify a human being. However, this attempt failed, ultimately resulting in the loss of Edward’s left leg and right arm and Alphonse’s entire body. In a desperate effort to save his brother, Edward sacrificed his right arm to affix his brother’s soul to a suit of armor. Some days later, an alchemist named Roy Mustang visits the Elric brothers, and he tells Edward to become a member of the State Military of the country to find a way to recover their bodies. After that, Edward’s left leg and right arm are fitted with two sets of automail, a type of advanced prosthetic limb, created for him by his close family friends Winry Rockbell and her grandmother Pinako.

Soul Eater

Soul Eater primarily revolves around students classified as meisters at the Shinigami Weapon Meister Vocational School , or Shibusen for short, located in the fictional Death City, in Nevada, United States. The school is run by Shinigami, the God of Death himself, as a training facility for weapons and the human wielders of those weapons, the meisters. Each meister has at least one demon weapon companion which has both a weapon and human form. Shinigami created the school as an organization that enforces peace in order to prevent the rebirth of the “kishin” , the evil demon god that nearly destroyed everything by plunging the world into chaos. Human souls that have become evil by straying from the path of humans have a high risk of becoming kishin, so evil humans are constantly being hunted down and killed by the students trained at Shibusen. The ultimate goal of the students with their weapons is to have their weapons defeat and absorb the souls of ninety-nine evil humans and one witch, which will dramatically increase the power of the given weapon and thus be capable of being used by shinigami. In order to ensure this is done in a timely manner, all students and weapons attend classes regularly and are given homework or supplementary lessons to further their training. The meisters have a rating system that goes from one to three stars which usually measures soul energy. It is important that the meister and weapon can tune their “soul wavelength” to perform high level attacks and bring out the weapon’s full power.

D-Grayman

Set during the end of a fictional nineteenth century on Earth, D.Gray-man mostly centers around 15-year-old Allen Walker. In his childhood Allen was abandoned by his parents due to a ‘deformed’ left arm and was adopted by a man called Mana Walker. At some moment Mana died and Allen tried to revive him with the help of a person called Millennium Earl. Allen revives him but Mana reappears as a akuma (Demon) that is ordered by the Millennium Earl to kill him. During that moment Allen is gifted with the ability to control a weaponized form of a divine substance from ages past, called Innocence and accidentally kills Mana. Before Mana dies, he curses Allen’s left eye, which later gives him the ability to see the souls of akuma. After that Allen discovers that the Millennium Earl tries to trick those who have lost loved ones to turn their dead souls into akuma and decides to train himself in order to stop him. Soon he becomes an Exorcist from the Black Order, a secretive organization which aims to stop the plan set in motion by the Millennium Earl and to save the souls trapped as akuma. However, the Earl has raised an army of akuma, created by taking advantage of grief over a loved one’s death, and summons the direct descendants of Noah himself, the 13-strong Noah Clan, to aid him in his second attempt. Because of the akuma’s ability to wear a human’s skin, they are nearly undetectable by any human. Allen proves to be a powerful asset as his ‘cursed’ left eye is able to detect the akuma.
